The working principle is mainly through the action of drilling pressure and drill string rotation, causing teeth to crush and eat into the rock, while generating a certain amount of sliding and shearing the rock. During the drilling process, the cone bit not only has an impact effect, but also has the function of crushing and shearing the rock in the formation, so it can adapt to various soft, medium, and hard formations.
